Abstract
Abstract A data recording device for incorporation in a camera which enables appropriate data associated with a particular subject to be recorded in the same frame on a film or at an appropriate position outside of the frame on the film in the camera by removably inserting therein a data capsule including data rings bearing the data to be recorded. The selected data are illuminated by means within the capsule and projected onto the film through a projection lens located in the camera body. This projection lens is automatically covered or sealed by a mirror on a spring-loaded lever when the data capsule is removed from the camera so that external light is prevented from entering the projection lens and passing onto the film. On the other hand, the projection lens is automatically uncovered to project the selected data which is reflected by the mirror when the data capsule is inserted into the camera.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
210 words
A data recording device for use with a camera of the type having: a camera body with an interior film plane; shutter means for controlling the admittance of light to said film plane; signal means actuated by said shutter means to produce a signal when said shutter means is opened; wherein the improvement comprises a combination of: a data capsule including: means for providing indicative data; means for illuminating said indicative data; means in said camera body defining a receptacle for said data capsule including: means for admitting illuminating light from said indicative data onto said film plane; means for shielding said light admitting means in the absence of said data capsule in said receptacle comprising a reflecting mirror for redirecting illuminating light from said indicative data through said light admitting means; means actuated by the insertion of said data capsule into said receptacle for displacing said shielding means to admit illuminating light from said indicative data to said film plane through said light admitting means; and means for actuating said illuminating means in response to a signal from said signal means when said data capsule is in said receptacle such that illuminating light from said indicative data is admitted to said film plane when said shutter means is opened.
Claim 2
Dependent Claim
210 words
A data recording device for use with a camera of the type having: a camera body with an interior film plane; shutter means for controlling the admittance of light to said film plane; signal means actuated by said shutter means to produce a signal when said shutter means is opened; wherein the improvement comprises a combination of: a data capsule including: means for providing indicative data; means for illuminating said indicative data; means in said camera body defining a receptacle for said data capsule including: means for admitting illuminating light from said indicative data onto said film plane; means for shielding said light admitting means in the absence of said data capsule in said receptacle comprising a reflecting mirror for redirecting illuminating light from said indicative data through said light admitting means; means actuated by the insertion of said data capsule into said receptacle for displacing said shielding means to admit illuminating light from said indicative data to said film plane through said light admitting means; and means for actuating said illuminating means in response to a signal from said signal means when said data capsule is in said receptacle such that illuminating light from said indicative data is admitted to said film plane when said shutter means is opened.
Claim 3
Dependent Claim
77 words
A device as in claim 1 wherein said means for providing indicative data comprises: a rotatable data ring member having indicia marked on its circumference; a window in said data capsule through which a portion of said indicia can be viewed; a rotatable setting ring member connected to said data ring member for rotation therewith such that the portion of said indicia viewable through said window can be changed by a rotation of said setting ring member.
Claim 4
Dependent Claim
31 words
A device as in claim 2 wherein said data ring member is of translucent material and said illuminating means is positioned to project light through its circumference and out said window.
Claim 5
Dependent Claim
40 words
A device As in claim 1 wherein said means for illuminating said indicative data comprises: a lamp; a power source for lighting said lamp; and a circuit for controlling the supply of power from said power source to said lamp.
Claim 6
Dependent Claim
59 words
A device as in claim 4 wherein said means for actuating said illuminating means comprises: a first contact means in said camera body connected to said signal means; and second contact means in said data capsule cooperating with said first contact means when said data capsule is inserted in said receptacle for connecting said signal means to said circuit.
Claim 7
Dependent Claim
25 words
A device as in claim 5 including means on said camera body for opening the connection between said first contact means and said signal means.
Claim 8
Dependent Claim
31 words
A device as in claim 1 wherein said means for displacing said shielding means comprises spring-loaded lever means having means thereon engagable by said data capsule for displacing said lever means.
Claim 9
Dependent Claim
16 words
A device as in claim 7 wherein said shielding means is mounted on said lever means.
